501N21A DE-SERIES SPICE Model (Preliminary)
The DE-SERIES SPICE Model is illustrated in Figure 1. The model is an expan-
sion of the SPICE level 3 MOSFET model. It includes the stray inductive terms
LG, LS and LD. Rd is the RDS(ON) of the device, Rds is the resistive leakage term.
The output capacitance, COSS, and reverse transfer capacitance, CRSS are mod-
eled with reversed biased diodes. This provides a varactor type response neces-
sary for a high power device model. The turn on delay and the turn off delay are
adjusted via Ron and Roff.
